From what I've researched this appears to be an awesome solution for increasing hydrogen production.

How is this possible?

A company called QuantumSphere out of California, USA has invented a unique process that causes the surface area of metal to increase up to 1000 times!

QuantumSphere's nanoparticles are available in four formulations: nickel cobalt, iron cobalt, nickel iron and silver copper.

“QuantumSphere’s plan is first to retrofit existing electrolysis equipment with its nanoparticle electrodes to boost efficiency. Next, it intends to partner with original equipment manufacturers to design at-home and on-vehicle electrolysers for making hydrogen from water for fuel cells. Finally, the company wants to work with fuel cell makers to replace their expensive platinum electrodes with inexpensive stainless-steel electrodes coated with nickel-iron nanoparticles.” - EETimes R.

"Santa Ana, Calif. - February 25, 2008 - QuantumSphere, Inc., a leading manufacturer of nano metals and alloys for applications in renewable energy, portable power, defense, electronics and other markets demanding advanced materials, today announced that it has achieved a breakthrough in clean hydrogen production through water electrolysis. Leveraging a proprietary advanced catalyst formulation, QSI-Nano NiFe™, QuantumSphere has effectively increased the surface area of commercial electrodes by approximately 1000 times. This increase is due to unique physical characteristics of nanoparticles. For example, a gram of QSI-Nano¨ materials have the surface area of about the size of a soccer field. To date, the QSI-Nano NiFe™ coated electrodes have surpassed 1000 hour durability testing under harsh conditions (33% KOH, 1 A/cm2). These nano-enabled electrodes demonstrate QuantumSphere's ability to produce larger amounts of clean hydrogen on demand at improved rates."

Supposedly, their process of nanometal coating can adapt to existing electrodes to increase the performance of up to 85 percent. The DOE (Department of Energy) has a goal of only 10 percent increase of performance by 2010.

If you want to make a hydrogen generator or you have already built one, you may want to consider purchasing their product.

Allow me to restate that you should be able to increase your hydrogen gas production and consume less power in doing so. This should take you to an even more advanced level of saving money at the pump. Who knows, maybe you'll make a hydrogen generator that is so efficient and you won't have to put gas in your car anymore? Well, perhaps in 20 years?

When you are ready to make a hydrogen generator please note the following if you decide to experiment with their product.

Here are QuantumSphere's Recommendations for Using their QSI-Nano® NiFe Coated Electrodes in Water Electrolysis

Electrode spacing: 0.375" or less. Spacing should be small enough to minimize resistance from electrolyte, yet not too small where the H2 and O2 bubbles increase resistance from obstruction of ion current.

Voltage/Current: Voltage will typically be a little above 2V per cell and decrease to below 2V as temperature increases from room temperature to 80 ºC (176 ºF). A current density range from a few mA/cm2 through 500mA/cm2 is acceptable. The specific voltage/current behavior strongly depends on cell and stack design.

Note: The nano coated side of the electrode is the cathode (negative, hydrogen producing) electrode, and in a bipolar stack arrangement must be facing the adjacent anode. This polarity is important for correct operation of the electrodes. In a single cell arrangement, simply ignore the middle electrode.

The raw materials are about $2 an ounce if I remember correctly. And of course their research and development is way more than that. So the end product is under $100 I believe. So, perhaps you could make a hydrogen generator using their patented technology.
